Hi, this addon really needs get updated, i absolutely love it. Does exactly what i want it to do and nothing else. But atm it's just spitting out errors whenever i use it which sucks real hard. I would love to be able to use this again!

I couldn't figure out how to get it to show both the raid frames and the party frames at the same time without it bugging out(party frames would randomly disappear, or interface errors would pop up).

You can however go into the interface options under the 'Unit Frames' category and enable the bottom option: Use Raid-Style Party Frames. This will disable the classic party frames and enable the new raid frames.

You might have some luck with Perry Party Frame Fix to get both frames at the same time but I had issues with the frames disappearing in BG's.
